Product Overview
The TPE3 80-310 in-line centrifugal pump is specified for clean water circulation across commercial heating and cooling installations, district energy plants, and industrial utility headers. Operating with a 5.5 kW electric drive, the unit features inline DN 80 pipe connections that mount straight into active fluid transfer lines without requiring offset piping manifolds.
Hydraulic performance testing confirms a rated output volume of 1407 L/Min with an operational head rating of 20.17 m. The EN-GJL-250 cast iron volute casing handles system line pressures up to 16 bar. Internal fluid movement is driven by a durable Composite impeller fitted with a BQQE mechanical seal. Product net weight equals 74.6 kg.
The electric drive motor operates on a 3 x 380-500 V Three-phase power source drawing 10.3 Amps nominal operating current at 5.5 kW drive output. The pump processes clean, non-aggressive fluids across liquid temperatures between -25°C to 120°C under maximum working pressures up to 16 bar. Flanged connections feature matching DN 80 inlet and outlet porting.
Built with an IP55 dust and moisture resistant motor enclosure, the unit features Class F thermal insulation for reliable continuous duty. An integrated variable frequency drive (VFD) and PI controller adjust motor speed dynamically to match real-time flow demand. Servicing is simplified by the top-pull-out architecture, allowing removal of the motor head and rotating assembly without disturbing main line pipe joints.
Features
- High-efficiency motor design delivers optimized hydraulic throughput with minimal electrical power consumption across variable duty cycles.
- EN-GJL-250 cast iron volute housing provides robust pressure containment up to 16 bar in demanding hydronic circulation loops.
- Corrosion-resistant Composite impeller rotor is precision-balanced to minimize operational vibration and extend bearing lifecycle.
- Standardized DN 80 flanged connections comply with EN 1092-2 for seamless drop-in integration into commercial pipe headers.
- Maintenance-free BQQE mechanical shaft seal prevents fluid leakage and maintains seal integrity under elevated working pressures.
- IP55 motor enclosure protection guards internal electrical components against ambient dust accumulation and water splash ingress.
- Class F thermal motor insulation permits continuous operation under elevated fluid temperatures ranging from -25°C to 120°C.
